Can I see these constellations in the winter sky?

Is Orion visible in the Northern Hemisphere during winter (well I know it is but am I seeing it from the Southern Hemisphere)? How about Big Dipper and Little Dipper? I just wondered because I was looking outside at night and I could see Orion, but it was due North, then as it got later, it went South (or maybe Earth did, I don't know) and I couldn't see the constellations Big Dipper and Little Dipper. When are these constellations visible in the Northern Hemisphere.
